Happy Pi Day! Mix in a little St. Patrick's Day fun into your celebration

Pi Day, celebrated on March 14—as in 3.14, get it?—has been commandeered in recent years by baking enthusiasts, who see the nerdy math holiday as the perfect opportunity to make a pie. This year, it falls on the Friday leading into St. Patrick’s Day weekend, adding up to the perfect chance to combine the two into one fabulous food event. Mix and match these Irish-inspired pies to create a full St. Paddy’s Pi Day menu. Some are sweet, some are savory and only one of them is green.

Orange whiskey souffle pie

Don’t be scared of this ‘souffle’ from New York food blogger Ken Leung. Yes, it uses eggs as a leavening agent, but unlike a classic soufflé, he says that “you don’t have to worry about it staying ‘inflated.’” This pie gets double Irish points for the inclusion of whiskey and potatoes.


1-1/2 cups (10-1/2 ounces) granulated sugar, separated
1 teaspoon orange zest, freshly grated
1-1/4 cups (8 ounces) Yukon gold potatoes, mashed
8 tablespoons (1 stick) unsalted butter, melted, plus more for preparing pan
4 tablespoons almond flour
1 teaspoon pure vanilla extract
1 teaspoon pure almond extract
1/2 teaspoon orange extract
6 eggs, 5 eggs separated, one whole
4 ounces whiskey, preferably Irish
